'brator or carrier, which terms, as used herein,

comprehend any device operable by the printing keys for moving theribbon to cover and uncover the printing point.

One object of my invention is to rovide an improved construction whereina 1'1 bon having a plurality of fields of different characterunder theinfluence of a printing key, be moved to cover the printing point withany desired field of the ribbon.

Another object is to provide means to dispense at will with thecrosswise feed of the ribbon in that class of machines em loying aribbon vibrator and wherein the ribbon has both a crosswise and alengthwise feed.

An additional object is to provide means for enabling a ribbon of morethan one color to be used in the last named class of machines.

Other objects will appear in the course of the following specification.

To the above ends the invention consists in the features ofconstruction, combinations of devices and arrangements -of parts .to behereinafter more fully described and particularly ointed out in theclaims.

In t e accompanyin drawings, Figure l is a vertical longitudinasectional view of a typewriting machine embodying my invention, certainparts of the machine being omitted. Fig. 2 is an enlarged detail view ofa part of the ribbon mechanism. Fig. 3 is a front elcvatidh of themachine showing the keyboard sectioned away, parts of the machme beingomitted and other parts being broken away.for the sake of clearncss. Fig. 4 is an enlarged fragmentary side elevation of parts'of the ribbonmechanism, certain parts being shownin section. Fig. 5 is a rearelevation of the parts shown in Fig. 4. Fig. 6 is a view correspondingto Fig. 1 but showing certain'of the nuts in different rclatitms fromthose in whidh they appear in said Fig.

4. Fig. 7 is a rear elevation of the parts shownin Fig. 6.

My invention is shown as embodied in a Monarch typewriting machine, butit is to be understood that it may be adapted to other forms of writingmachines.

In the drawings, 1 is the base of the machine support ng corner posts 2which sustain a top plate 3. Key levers 4 arefulcrumed on a fulcrumplate 5 and each key lever is provided with a restoring spring 6.

Pivoted at 7 to each key lever is' a sub-lever 8, the lower portionwhereof coacts with a fixed abutment 9 and the up er end whereof isconnected by a link 10 wit a type bar 11. Each type bar is pivotallymounted in a hanger 12 which is one of a series of hangers arranged in asegment of a circle on a segmental type bar support 13. The type barsare normally supported at their outer ends by a segmental type rest 14and said bars are adapted to cooperate with a' platen 15' mounted in acarriage 16, said carriage being guided and supported by anti-frictionballs 17 which cooperate with grooved rails 18 on the carriage and withoppositely grooved rails 19 secured to brackets 20 fixed to the topplate of the machine. A feed rack 21 is mounted on the carriage andnormally meshes with a feed pinion 22, the latter being operativelywheel 23.

Adapted to cooperatewith the escapement wheel are feed dogs 24 at thetop of a pivoted dog rocker 25, said dog rocker having a horizontallydisposed arm 26 which is connected by a link 27 with a universal barframe 28, the latter being )ivoted in the base of the machine at 29. heframe 28 carries a universal bar 30 which extends from side to side ofthemachine beneath the series of key levers '4 and'the spacinglevers'(not shown) and is adapted to be actuated by said levers whenthey are depressed during printing or spacing operations. The carriage16 is connected by a band 31 with a spring drum 32 which tendsconstantly to draw the carriage across the machine to the left, so thatwhen the universal bar 30 is operated the cscapement mechanism justdescribed is caused to be actuated in a known manner to permit of letterspace movements of the carriage.-

Ribbon spools 3.53, arranged above the top plate 3 at each side of themachine and forconneeted with an escapement,

wardly of the platen, receive a ribbon 34 which, as herein shown, isdivided longitudinally. in-to stripes or fields a and?) of differentcharacteristics; for example, the field a may be of one color such asblack and the iield b of a different color, as red, or the field a maybe copying ribbon and the field I) record ribbon. The ribbon 34 may befed longitudinally from either spool to the other by any suitable means,that illustrated in the drawings having the general characteristics ofthe ribbon feeding mechanism of the Monarch machine. Each ribbon spool33 is carried by and turns with an upright shaft 35 which rotates in afixed bearing 36 and has secured at its lower end a small beveled gear37. The gear 37 meshes with a beveled pinion 38 secured to the forwardend of a horizontal shaft 39, which shaft carries at its rear end abeveled pinion 40, the latter being adapted to mesh with a beveleddriving pinion 41 mounted on a driving or power shaft 42, having itsbearings in lugs 43 depending from the top plate. Rotary movement istransmitted to the shaft 42 through beveled pinions 44 and 45, the

pinion 44 being operatively connected with the driving shaft and thepinion 45 being operatively connected with the spring drum 32. It willbe understood that each ribbon spool is connected with a gear train likethat above described, each of said gear trains being adapted to beactuated from a driving pinion 41 on the driving shaft 42. 1twillfurther be understood that the driving shaft 42 is capable oflongitudinal movement andthat the longitudinahposition of said shaftdetermines which driving pinion 4 I will be in. mesh with itscooperating pinion 40 and which ribbon s ool will be turned to wind theribbon,

t ereon. 7

Midway between the ribbon spools, the ribbon 34 is threaded tl'irough aribbon vibrator or carrier 46 which is guided and supported in theupright arms 47 of abracket 48, the latter beingsecured to the top plateby screws 49. The loweriortion of the vibrator 46 is bifurcated andprovided with a cross pin. 50 bridging the bifurcation, said pin beingengaged by the slotted forward end of an operating lever 51 pivoted at52 in a lug 53 depending from the under side of the top plate. The reararm'of the operating lever 51 is formed with an elongated slot 54 andengaging with this slot is a pin or stud 55 secured to the top of a link56, the lower end of said link being pivoted at 57c) the universal barframe 28. Near its upper'end the link 56 is provided with a forwardlyand downwardly bent arm 58.

The link 56 is adapted to be swung about its pivot 57 in order to causethe stud 55 to move longitudinally in the slot 54 so as to engage the.operating lever 51 at varying distances iron; its 'pivet or inlcrum 52and thereby to varyt'he tl' t-ow jf the ribbon carrier or vibrator 46.'This swinging or vibratory movement. of the link. 56 is caused by aneccentric member 59 which is slidably mounted on the driving shaft 42and which is adapted to cooperate with the strap formed bythe link '56and its bent arm 58. The eccentric member 59 comprises a narroweccentric working face 60, a tapered or cam portion 61 and a sleeveportion 62, the latter being formed with a circumferential groove ordeis here shown an arm 66 having a fork 67 at its lower end and a collarportion (58 at its upper end. The fork 67 at the lower end of theswitching member 66 embraces or par tially surrounds the depression 63in the eccentric member 59.

ber 59 is adapted to he slid longitudinally of the shaft 42 and into andout of cooperative engagement with the link 56 by means of the switchingmember (56, the collar portion (58 of which is secured to the inner endof a slide rod 69 by a set scerw 70. The slide rod (it) has its bearingsin the right-hand lug 43 of the ribbon dr1vm shaft and in a rwhtangledbracket 71 which is secured to the hand end of a rock shaft 77 mountedto turn The eccentric memin the depending bearing arms 78 -of a U.

end to the link 27 of the carriage feeding mechanism, and said springtends constantly to draw the link 56 rearwardly away from the fulcrum 52of the operating lever 51.

The outer or right-hand end of the slide rod 69 is provided witli acollar 84 carrying is) I toral plate extending to the left and dow 11 ain 85, which is embraced by the fork of a ifurcated crank arm 86 fixedlysecured to the rear end of a horizontally disposed and forwardl fextendim rock shaft 87 Fi s. '2 .l s c,

and 33 The rock shaft 87 extends through and terminates slightly infront of the front plate 58 of the machine. A crank arm 96 is secured bya headed screw 89 to the front end of the rock shaft 87 and is providedwith a finger piece or handle 91 and terminates at its free end in apointer 9'2, said pointer being adapted to cooperate with indicatingmarks (as the letters N, B and lt) formed preferably on the front faceof the plate S8. The rock shaft 87 has its bearii'igs in bearing plates93 \\hich are secured to lugs 94 which bear the right-hand ribbonfeeding sha ft 39, said bearing plates being fixed in place by headedscrews 95. A collar 96 is secured to the rock shaft 87 and abuts againstthe rear face of the forward bearing plate 93, and integral with saidcollar is a positioning member 97 which, herein shown, is in the form ofsecwardly from the rock shaft 87 and having its periphery fori'n-cd withdepressions or notches 98, 99, 100 (Fig. 2). A detent or locking spring191 is fixedly secured to the under side of the top plate in anysuitable manner and isadapted to engage the depressions or notches inthe positioning member 97.

The operation of the mechanism above described will now be brieflyexplained. Suppose that the parts be positioned as in( icated in Figs.1, 2 and 3 with the indicator or pointer 92 pointing to the indicatingmark N (which means nonnal) on the, front plate 88, the sectoralpositioning member 97 will be engaged by the detent 101' and the sliderod 69 will he in its extreme left-hand position with the positioningmember 66 causing an engagement or coeperation between the eccentricface 69 of the member 59 and the strap in the link 56. When the partsare so arranged the rock shaft 77 and the crank arms 76 and 81 will,during part of the time, be maintained by gravity in the positionsindicated in Figs. 1 and 3, with the crank arm 81 in a substantiallyvertical position and the crank arm76 in a substan- 'tially horizontalposition. During the operation of the macl'nne, however, the rota tionof the eccentric face 60 moves the link 56 progressively towards andaway from the fulcrum 52 and will sometimes swing the link 56 far enoughrearwardly to cause it toengage with the roller 82 to swing the arm 81rearwardly to rock the rock shaft 77 and bring the arm 76 very close tothe slide rod 69. With the positioning; mechanism arranged as now beingconsidmed, the ribbon will be fed longitudinally and will also be givena variable (;i ).-;S\VlSU feed, so that the type impressions Wlll followa serpentine or I wavy path lengthwise of the ribbon and we tending froms de to side thereof as is charmachine. If a ribbon of uniform character1 be in place in the machine, a ribbon having a plurality of fields ofdifferent characteristics, such as the ribbon 34, may be substituted forthe uniform ribbon in a known manner. Should the mechanism still beallowed to remain in the relations indicated in 5 Figs. 1-3, inclusive,some of the type impressions will now be printed, say in black, othersin red, and others partly in black and partly in red, giving avariegated or articolored effect which is sometimes desirable inornamental typewriting. Usually, however, it is desired to print all theletters of a word or a succession of words in one color.

If it first be desired to print in black alone, the handle 91 is pressedto the right until the pointer 92 points to the letter B (indicatingblack). on the front plate 88. By this movement the rock shaft 87 isrotated rightward and the notch 99 in the sectoral plate is engaged bythe detent 161. At the same time the slide rod 69 is slid rightward inits bearings, causing the member 66 to act on the eccentric member 59 tomove the latter rightward along the driving shaft 42 to the positionindicated in Figs. 4 and 5, which atter view, it will be recalled, is arear View. It will be noted that by this movement the eccentric face 60is disengaged from the strap in the link 56, whereupon the latter isswung rearwardly by spring 83 carrying with itthc crank arm 81. Therearward movement of the link 56 continues until the rotation of therock shaft 77 by the crank arm 81 brings the crank arm 76 into contactwith the sliding rod 69, thereb preventing further movement of the cranarm 81 and the link 56. During subsequent printing 0 erat-ions the link56 will be maintained wit the stud 55 at the rear of the slot 54 in theoperating lever 51 and as far as possible from the fulcrum 52 of saidlever. The link 56 as it roller 82 at the end of the crank arm 81. The

;wit h the stud 55 maintained at the rear of {the slot 54, the operatinglever will have a constant throw and the ribbon vibrator 'will be movedthereby so as to cause the field a on theplaten. The path of the typeimpressions will be. in a strai ht line longitudinal of said. field a.It will be noted from an inspection of Fig. 5 that the described slidingmovement of the rod 69 has served to bring the cam member 74 close tobut not actually in engagement with the crank arm 76. It will further beseen from an inspection of said figure that cndwise movement of the rockshaft 77 in either direction is moves up and down has a bearing ontheacteristic of the ribbon feed of the Monarch parts are so arrangedand proportioned that or the black field to cover the printing pointprevented by the contact of the crank arms' 76 and 81 with the bearingarms 78 of the bracket 79. i

If it be desired to print upon the red field ol' the ribbon, the lingerpiece 91 is pushed still l'url her to the right until the pointer 92'.rcgisters with theletter R (meaning cated. in Fig. 7, while at thesame. time the cam lace 75 of the member 74 contacts with the crank arm76 and raises th e latter to the circular law 75, rocking the groekshaft 77' 'and swinging the-crank vorrn 8] forward.

fit

As the crank arm 8] is swung forwardly it pushes the link 56longitinlinally of the lever 51 against the: force of the spring 83 andcauses the stud to engage the slot 54 near its l'orward end and close tothe fulcrum 52 ol the operating lever. The parts will now be positioned.as indicated in Figs. (5 and 7, and during the operation of the machinethe link 56 will be moved up and down against the roller 82, and theposition of the stud 55 in respect to the iulcrunr52 will not varyappreciably. Qonserpiently the throw communicated to the ribbon vibratorby the operating lever 51 will be a constant one; and tie parts are soproportioned and adjusted that this constant throw will cause the fieldI) or red held of the ribbon to always be brought to the printing point.The path of the type impressions wil tudinal of said red lield b.

By reversing the operations above 1 described the black field or theentire surl'aeeol' th.e ribbon may again be brought into play asdesired.

ltwill be noted that in my in'iproved con struction otribbon leedingmechanism l cmploy a single operating lever and a single link which isin constant engagement with said lever; that the link is movedlongitudinally of the lever by both the eccentric member 55) and themember 'eomprising the rock shaft 77 and the crank arms 76 and Slflvhichlast member is in ell'cct'a bell crank lever (omprising? arms 76 and 81and an elongated pivot 77; that the bell crank member positions the link56 indepmidcntly ol' the member 5!), said bell crank member beinginoperative when the eccentric member 5.) is operative, and operatiw:when said eccentric member is inoperative.
